Question about Coldfusion 2021 update 10 install: I tried to install it through Coldfusion Administrator , It was running forever and show message "ColdFusion server will be stopped and restarted during installation.
Starting installation...this might take a few minutes
Install Status: Server taking too long to restart. You will have to manually restart server and check update status" .  After I restarted CF, the system info shows  '2021.0.09.330148".  The coldfusion 2021 update 10 was not installed. ? ?

I would try installing it manually.  You get no useful feedback when doing updates through the admin.

&gt; 1. Thanks Jim.  I am not  clear about the manually install steps, Could you please help me to correct it? We are using coldfusion(2021 Release, Enterprise, 2021.0.09.330148,Tomcat 9.0.60.0 ) .  1.  Do I need to to add  _"-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**;!org.jgroups.**;!com.sun.rowset.**" to JVM through CF admin?_  
&gt; 2.  _It says download '_hotfix-010-330161.jar. I did not see any steps to run and install this jar file. Since the UNzip repository folder includes this .  why do I need to download this file?   
&gt; 3. Update "packagesurl" in cfusion/lib/neo_updates.xml: can  i use relative url  (packageurl="/unziprepository/_bundles/bundlesdependency.json"_


1. You probably don't need this - it's for JEE installations only
2. You may be running into the update issue - Charlie has details here:  <https://www.carehart.org/blog/2023/7/21/problem_downloading_cf_updates_after_jul2023_jvm_update>
Details of where to download and how to run the required commands are here:  <https://helpx.adobe.com/coldfusion/kb/coldfusion-2021-update-10.html>   under the "INSTALL THE UPDATE IN OFFLINE MODE MANUALLY" section

Thanks Jim for the help. It is a big help. I was able to install this coldfusion 2021 update 10 with success. :slightly_smiling_face:
